[vtkusers] python (2.7) problems compiling with MSVC 2010 64bit

[David Gobbi]

Hi Dominik,

The "site" module is the first to be imported, so if it is missing,
then the "PYTHONHOME" (or equivalent) is not set or is incorrect and
python is unable to find its own modules.

If you set PYTHONHOME manually (i.e. as an environment variable) to
the directory where python-2.7 resides, then I am guessing that these
tests will pass.

So... the next question is, why is this happening?  Evidently the
vtkpython executable is missing some critical information that allows
it to find the python-2.7 directory on its own.  The relevant code in
VTK is Wrapping/Python/vtkPythonAppInit.cxx

None of the dashboard machines seem to use python-2.7.
